Electrical connector

Abstract

An electrical connector comprises an insulating seat, a plurality of conductive terminals inserted on the insulating seat, and a cage covering on the insulating seat. The insulating seat comprises a body, a tongue plate projecting forward from the body for the arrangement of the conductive terminals, and a bottom plate extending along from the body under the tongue plate. The cage includes a bottom wall located between the tongue plate and the bottom plate of the insulating seat. The electrical connector further comprises a securing part for securing the insulating seat. The securing part comprises a main body abutting above the bottom plate of the insulating seat and two soldering parts bend downwards and extending from two ends of the main body respectively.

The invention claimed is: 
     
       1. An electrical connector comprising
 an insulating seat, this insulating seat comprises a body, a tongue plate extending forward from the body and used for the installation of the conductive terminals, and a base plate extending forward from the body and positioned under the tongue plate 
 a plurality of conductive terminals inserted on the insulating seat, and 
 a cage installed on the insulating seat, the cage having a top wall, two side walls, and a bottom wall, and the bottom wall of the cage is positioned between the tongue plate and base plate of the insulating seat; wherein the two sides of the front portion of the cage each bend and extend out into locking arms, and these two locking arms are locked to the base plate of the insulating seat; this electrical connector also comprises a securing part to secure the insulating seat, and the securing part comprises a main body abutting the top of the insulating seat's base plate and two soldering portions bending and extending downward from the two ends of the main body. 
 
     
     
       2. The electrical connector of  claim 1 , wherein the top surface of the base plate of the insulating seat is equipped with step portions that are low in front and high in back, and the back end of the main body of the securing part presses against the front edge of these step portions. 
     
     
       3. The electrical connector of  claim 2 , wherein the base plate of the insulating seat is equipped with at least two grooves that extend longitudinally; the main body of the securing part comprises multiple compression portions and bent portions arranged between neighboring compression portions and protruding downward; the compression portions are arranged between the base plate of the insulating seat and the bottom wall of the cage, and the shape of the bent portions corresponds to the grooves, and they press into the grooves. 
     
     
       4. The electrical connector of  claim 1 , wherein the base plate of the insulating seat is equipped with at least two grooves that extend longitudinally; the main body of the securing part comprises multiple compression portions and bent portions arranged between neighboring compression portions and protruding downward; the compression portions are arranged between the base plate of the insulating seat and the bottom wall of the cage, and the shape of the bent portions corresponds to the grooves, and they press into the grooves. 
     
     
       5. The electrical connector of  claim 4 , wherein the back portion of the cage extends downward into two soldering arms. 
     
     
       6. The electrical connector of  claim 1 , wherein the locking arms of the cage first bend downward from the two side walls of the cage then inward, and these two locking arms are locked to the two outer sides of the insulating seat's base plate. 
     
     
       7. The electrical connector of  claim 6 , wherein two outer side surfaces of the insulating seat's base plate have a fastening groove running longitudinally, and the front end of the fastening grooves are open, wherein the locking arms of the cage can be inserted from the front end of the fastening grooves and be locked inside the fastening grooves. 
     
     
       8. The electrical connector of  claim 7 , wherein the front end of the fastening grooves has a lead-in ramp configured to guide the locking arms of the cage smoothly in from the front end of the fastening grooves. 
     
     
       9. The electrical connector of  claim 1  wherein the securing part is a metal part that has been stamped and formed. 
     
     
       10. The electrical connector of  claim 1  wherein the two soldering portions of the securing part bend downward and extend out to two outer sides of the insulating seat such that in operation they can pass through and be soldered to the positioning holes of a circuit board.
